IMPROVEMENTiIN THE M'ANUFAGTURE OF GAS.

Specification formingpart of Letters Patent No. 58,22 l, dated September "5, 1866.

To all whom it may concern:

Be it known that I, J osErI-r H. CoNNELLY, of Wheeling, in the countyof Ohio and State of West Virginia, have invented a new and useful Improvement in the Manufacture of Gras from Goal and Oil; and I do hereby declare the following to be a full, clear, and exact description of the nature, construction, and operation of the same, reference being had to the accompanying drawings, which are made a part of this specification, and in which- Figure 1 is a sectional front elevation of my improved apparatus, the line w w, Fig. 2, indicating the plane of section. Fig. 2 is a vertical longitudinal section on the line yy, Fig. 1.

Similar letters of reference indicate corresponding parts in the different figures.

This invention relates to an improvement on a process for using petroleum as a fuel, which is fully described in Letters Patent granted to Joseph H. Connelly and Joseph W. Phillips January 21, 1862, and numbered 34,198, and which consists, essentially, in forcing, by means of a jet of steam, petroleum or its products over the incandescent coal or wood or other fuel used in steamboiler 0r other furnaces. l

This invention also relates to an. improvement on a process for using` petroleum and its products, combined with lime and salt, and forced into any furnace with ajet of steam in the form of spray, for the purpose of desulphurizing coal for manufacturing' iron and other purposes, and described in Letters Patent granted to Joseph H. Connelly August 9, 1864, and numbered 43,760.--

The object of the present improvement is the adaptation of the above to the manufact-ure of gas; and the process hereinafter .de-

scribed involves the same principles as those covered by the two above-mentioned patents. By this process the obnoxious odor orfumes of the sulphur is destroyed by the lime used in the purifier when exposed to the air; also, the gas thus produced is increased in richness or illuminating power by at least one-fifth, and the coke from the coal used in the retort, which is charged with the same quantity of coal as if the oil and lime-water were not used, is freed from sulphur and rendered suitable for manufacturing purposes. Furthermore, the expense of manufacturing the gas is largely reduced, and the retorts are only required to be charged with coal half as often as under the ordinary processes.

In order that others skilled in the art to which my'invention appertains may be enabled to fully understand and use the same, l will proceed to describe it in mdetail with ref erence to the accompanying' drawings.

A represents the retort. B represents the escape-pipe for conducting the gas to the hydraulic main. C representsan iron spout at tached either by rivets or a flange to the mam head, and extending back above the coal the half length of retort, to receive the liquids and carrythem back to its center. G repre sents the seal or trap, with its funnel, to receive the compound of residuum and crude benzole. F represents the seal or trap, with its funnel, toreeeive the lime-water. E represents the pipe which receives the oil and limea water and conducts them into the escape-pipe B, said pipe E having a stop-cock, H, near its insertion, at which point the mouth of pipe E discharges itself in the center of esoapepipe B directly over the spout C.

The petroleum or its products and 1ime-w`a ter are forced in to the retort by means ot' a jet of steam, after the manner described in my patents hereinbefore alluded to.

O represents the oil-tank, provided with a cock, o, and L represents the tank, with its cock Z, for the lime-water.

The lime-water is converted into steam or vapor as it passes down and back on the iuclined surface of the spout attached to manhead, through which the gas from the coal must pass, said lime-water acting as a desulphurizer and purifier. The oil compound, being discharged at same point, and passinglback in conjunction with it, is converted into gas, which not only makes threefold more gas than the coal, but also neutralizes the sulphur and puries the gas from the coal as it comlnin-l gles in its ascension through the escape-pipe B.-

I propose to use about the proportion of three quarts to one gallon of the compound of oil with an equal quantity of lime-Water to one bushel of coal, the same being varied according to the quantity ofthe coal, as it is not designed to make more than one-third to onea half of the gas from the oil, as a greater proportion may condense, and thus again assume the form of oil' and make the gas too rich.

The pipes which conduct the liquid into the retort are represented as located at the front end'of the retort; but the liquid may be introduced by a similar arra-n gement at the rear or back end of the retort.

Having thus described my invention, the following is what I claim as new herein and desire to secure by Letters Patent:

l. The forcing of the petroleum or its prod nets-Viz., residuum and crude beuzole-in about equal quantities, iu conjunction with lime-water, into the retort with a jet ot' steam when the retort is charged with coal, substantially as described.

2. Introducing the petroleum or its products, in conjunction with lime-water, into the retort, when charged With coal, by means ot' the pipes F G, provided with seals or tra-ps,

substantially as described.

in conjunction with lime-water, into the retort,

when charged with coal, by means of the common receving-pipe E, inserted into the retort at or near the back end, either with the seals, traps, or steam-jet, substantially as described.
